Ground Source Heat Pumps Installers

A ground source heating system makes use of solar thermal energy that is naturally stored in the ground and use this as the heat source for your home.

At a Glance:

Much more efficient than traditional boilers

Not affected by seasonal weather

Low maintenance/running costs

Installation from around £7500

A little way below ground level the temperature remains fairly constant throughout the year, so our renewable energy installers bury a long loop of pipe into the ground through which a fluid is constantly circulated by the heat pump.

In a process known as thermal transfer, the liquid picks up a slight increase in heat from the surrounding ground as it flows through the pipe, and within the heat pump, this slight temperature increase is then stepped-up drastically via an internal refrigerant circuit, and the heat pump can then supply usable heat energy to your house.

Heat pumps themselves require electricity to run and operate, but for every unit of electricity they use, they efficiently produce up to four times as much heat energy output to your home - which in normal boiler terminology would make them nearly 400% efficient! Our team of designers can talk to you more about how efficient these systems can be.

There are a number of types of ground source heating system available to suit the heating requirements of any building, whether it's an existing structure or a new build. They can also be installed almost anywhere, provided there is sufficient space to lay the ground loops or to drill a vertical borehole.

The benefits of a ground source heating system

Enjoy independence from fluctuating (usually increasing!) costs of fossil fuels by no longer relying on gas or oil supplies.

If you have plenty of land then a ground source heat pump can be installed by our renewable energy installers with a horizontal collector, where lengths of pipe are buried underground to a depth of around 1 to 2 metres.

Alternatively, a vertical collector can be used, which requires a borehole to be drilled to a depth of up to 200m and the collector is fed into the hole.

Provides substantially more heat energy output than electrical energy used to run the pump.

Electrical and plumbing installation is very straightforward, requiring only a 240V mains supply and simple flow and return connections to the ground collector and to the house heating circuits.

A ground source heating system is at its most efficient when combined with low temperature underfloor heating systems, but can also be made to work well with conventional radiators.

All systems installed by R&M Green Energy Solutions will qualify for payments under the Government’s Renewable Heat Incentive and Renewable Heat Premium Payments.

Typical costs
The costs of installing ground source heating system into an average sized house would start from around £7,500, although often the hot water cylinder will also need upgrading additionally to act more as a thermal store for the heat pump.

Subsequent running costs for such a system would possibly be as low as £650 annually for all space heating and hot water requirements, and these running costs can obviously be further reduced by using solar panels in tandem with the heat pump as well.

There are a huge number of variable factors in determining costs for installations by our including the size of your home, how well insulated it is, and whether you have radiators or low temperature under floor heating, so we offer a free home survey to all customers in order to give you an accurate cost estimate for your own specific needs.
